CAR-COU PLI NG.A

SPECIFICATION forming part of Letters Patent No. 461,540, dated October20, 1891.

Application led June 6, 1891. Serial No. 395,292. (No model.)

To all whom t may concern:

Be it known that I, ARNOLD HENRY BLANK- MAN, a citizen of the UnitedStates, residing at Alton, in the county of Wayne and State of New York,have invented a new and useful Oar-Coupling, of which the following is aspecification.

This invention relates to car-couplings, and more especially to thatclass thereof known as twin jaw, and the object of the same is to effectcertain improvements in the manner of operating the jaws.

To this end the invention consists in the specic details of constructionhereinafter more fully described and claimed, and as illustrated onthe'sheet of drawings, wherein- Figure l is a perspective view takenslightly from the ,under side and showing the end of the car providedwith myimproved coupling. Fig. 2 is an end elevation of the car with thedraw-head retracted. Fig. 3 is a right side elevation.

Referring to the said drawings, the letter O designates the bod y of thecar, beneath which are secured two blocks B, having outwardlycurvedadjacent faces F, between which is loosely mounted the enlarged androunded rear end E of the draw-head D. The latter has at its front end abeveled jaw J of any approved type of twin-jaw car-coupling, and aspring S beneath the car draws the body of the draw-head laterallyWithin a transverse slot T in the dead-block in aproper direction tocause the jaw .I to engagea similar jaw on another car.

W is a wheel eccentricallypivoted, as at P, to the end of the car abovea retaining-stop R, which limits its movement, and the periphery of thiswheel is grooved, as seen at G in Fig. 3, a chain N leading from thedraw-head partially around the periphery of this'wheel and connectingwith an eye I therein. The vertical rod V is connected to a crank-pin Kin this wheel about at the -point shown, and its upper end is forked andpivoted to the front end of a lever L, which is mounted on an upright U,rising from the top of the car.

In operation, when the lever is moved bya brakeman standing on the topof the car, so as to depress the rod V, the wh eel XV is turn edoutwardly, as shown inFig. 2, and the tension ofl the chain N as it iswound over the groove G draws the draw-head D to one side within thetransverse slot T and disengages the jaw J from a similar jaw on theother car. Upon releasing the lever the spring S causes the parts toassume their norm-al positions. At this time the wheel V has turned sofar over its pivot P and rests upon the stop R in such a manner that thedraw-head cannot be accidentally or automatically retracted, and hencethe undesirable uncoupling of the cars will not take place. Variouschanges in the details of construction may be made Without departingfrom the spirit of my invention. When it is desired to remove 'thedraw-head for any purpose,its enlarged and rounded head E is dropped outot' the space between the curved faces F of the blocksfB, andthe entiredraw-headand draw-bar is removed longitudinally through the slot in thedead-block. By this specific form of pivotat the rear end of thedraw-barI avoid the necessity for using any pivot-bolt,'although ofcourse, if desired, one might be used without affecting the balance ofthe invention.

Vhat is claimed as new isl. In a car-coupling, the combination,withblocks secured beneath the car-body and having outwardly-curved adjacentfaces, a slotted dead-block, a draw-head having an enlarged and roundedrear end looselymounted between said curved faces, its body passingthrough the slot in the dead-block and its front end having a beveledjaw, and a spring holding said draw-head wit-h its jaw in normallyoperative position, of means, substantially as described, for retractingthe drawhead against the tension of thespring, as set forth.

2. In a car-coupling, the combination, with a draw-head pivotallyconnected at its rear end with the car and having a beveled jaw at itsfront end and a spring holding said drawhead With its jaw in normallyoperative position, of a wheel eccentrically pivoted to the end of thecar at the rear side of said drawhead, a stop below said -wheel at apoint to allow the longest radius of said wheel to stand between itspivot and the draw-head, and means, substantially as described, forturning said wheel and retracting the draw-head, as set forth.

8. In a car-coupling, the combination, with ICO a. draw/:head pivotallyconnected at its rear connecting said lever with the crank-pin, as
